Nice animations and had an interesting concept, but I think the ending was not that uplifting as I hoped [spoiler](when the Dragon/Beast is found out to be a 14 year old with a younger brother to protect from an abusive father, only Suzu goes to Tokyo ALONE to confront him and protect the two children. And said confrontation is just her standing fearless in front of the abusive father, and he just... retreats scared? Then she goes back to her town and the two kids are still left in the care of their father! I mean, I'm pretty sure that is not safe and threw me off quite a bit...)[/spoiler]. The songs are nice, nothing exceptional, but pleasant to hear and see. The U world was a bit of a mess, tho'. There's a romantic interest that you can't quite pinpoint at first between three characters, but then it plays out in a very predictable way.
Also for some die hard Disney fans, there were some scenes that explicitly quoted Beauty and the Beast from the moment Bell/Belle finds the castle.
In short, Belle is a colorful movie about courage and inner strenght, but in the end it feels like it lacks something.
